Steps to configure local SSH security

-the login local subcommand defines the use of local usernames, replacing the login subcommand in vty configuration mode.
Step 2.
Tell the switch to accept both Telnet and SSH with the transport input telnet ssh vty subcommand. (The default is transport input telnet, omitting the ssh parameter.)
Step 3.
Add one or more username name password pass-value global configuration commands to configure username/password pairs.

Step 4.
Configure a DNS domain name with the ip domain-name name global configuration command.
